Why "At specified station" interrupt does not work?

[Viidi]

There is cargo in the car, it is located at the Depot station.
But it is not sent to Clean1.
I tried switching Automatic/Manual - no effect.
I also tried sending a train somewhere and returning it to Depot, but there is no effect.

What's wrong?

Interrupts are processed, when its waiting condition just became true and a train is about to leave a station and looking for a destination. In your case, the train is still waiting at the station for its waiting condition to become true. Additionally, your current depot waiting condition will never get true, because it has an invalid expression [Station] = (empty), so interrupts are not yet being processed and will never get processed as long as you don't fix that condition.

A better approach for interrupt design is to make the loading station as the one regular schedule entry. Not the depot, because in a busy system a train might never have to go to the depot, so such an entry as fixed entry is inappropriate. Going to the unloading station, going to refuel and going the depot would be implemented as interrupts, depending on train content, fuel content and station availability.

Thank you for your detailed response. Indeed, that was the problem.
